Hi Camm,
Certainly! At the beginning of a session, type numer:true - this will let
you do nearly everything in floating point. There is a routine in the share
directory for Newton's method for your nonlinear equation. I've done a few
numerical routines by essentially transcribing published Fortran or C codes.
